' j This invention relates to locomotive tender Figure 1 is a top plan viewof on'e form of;

tanks and the like,' and more particularly to the bottom construct-ions thereof. I j V I-Ieretofore, and asmore particularly set forth in my earlier Patent, No. 1,460,710, granted July 3, 1923, the'bot-tom' of the tender tank was built up of several sections, the side [edges of which were providedwith upstanding flanges secured together in overlapping relation. As the result'of more or less sudden starting and stopping of the locomotive tender, serious Water hammer effects are set up in the tank and unless the latter be strongly const-ructed, especially the jointsthereof, the

stresses and strains 'so' occasioned will tend to weaken the tank and spread the joints with injurious results.

' problem, resort has been had to the use of transversely disposed dash-platesfinthe tank.

*O Wing'to the considerable forces exerted on these plates by the fore anda'ft surging of the water, they need to be Secured rigidly in poflanges extending longitudinallyof the tank sition, and in the arrangementshown in the patent above referred'to, these plates are sup'' ported by suitable means upon the overlapped bottom. u

construct and assemble but which also in- Inthe present templates the provision of abottom unit for the tender tank whichisnot only simple to eludes joints between the several sections 'of the'unit whiehare of maxlmum strength and least subject to leakage. In furtherance'of.

this object the invention aims-to eliminate, the upstanding flanges heretofore employed. for securing the severalsections of the bottom to gethenit being contemplated in this instance 1 to weld these sections together. And in place of the intermediately arranged upstanding flanges it is an object of this invention to provide longitudinally extending reinforcing and strengthening ribs, these ribs being in, the form of independent members welded in p0 sition immediately above and overlying the joints between adjacent sections of the tank 'bottom.

'Referring more particularly to the drawmgs, 1t Wlll be seen thatt'he tank bottom 10 may be built up of one or more sections, arranged to lie substantially in a single horizontal planeQ'In the form shown in Figures 1 flanges 13. The longitudinally"extending igure 6 isa transverse section taken on the p par; viewertill Figure is a partial top plan view ofanothermodlfied form of tank bottom construeand Qthe bottom 10 iscomposed of three loni gltud nal sections 11, 11-and 12 provided along their outer edges with, upstanding side edges of the central section 12and the.

portions of the edges oft-he" outer sections- '11l1 which are opposite thecentral section are arranged in'abutting relation, as is-most clearly shown in Figure 2, in such manner that themeeting edges between the" several sections maybe butt welded together to form absolutely tight joints. Overlying" these welded oints l land extending substantially I over their entire lengths are a pair of mem bers15 ofsubst-antially inverted T shape,

these. members being. preferably welded in I position. A 'construction of tankbottom such V as just described is simple and inexpensive to k inanufactureat the same time that it is of maximum strength and least liable to leak.

- Further, the members 15 constitute the necessary longitudinally extending "reinforcing and strengtheningribsfor the bottom upon In the modified-form of construction shown I in Figures13'and4 the tank bottom 10 conmembers 19 are providedinthe construction i shown in Figure 1 but in this modified form which the transversely disposed dash'plates. (not shown) may bemountedin any suitable the T members are disposed on either side of the welded joint 18 and are welded di. rectly upon the'sections 16 and'17. As in the former instance the tank bottom is provided Withupstanding flanges 20 along the outer V edges thereof. 7 J

In F igures and 6 the tank bottom 10 is 1nv theform of a single stamping having theupstanding flange 21 extending around its outer edges.
